Three EQs. Three Completely Different Reasons to Reach for One.

An EQ is not just an EQ. Sometimes you want a graphic EQ you can grab and push by ear. Sometimes you want a parametric tool precise enough to trust on a master bus. Sometimes you don't want an EQ at all - you want an era, a room, a decade's worth of character applied in one move. The EQ Collection gives you all three, and none of them try to be the other two.

Third Rail is the creative one. A tube-driven 31-band graphic EQ with real ISO center frequencies, input-driven saturation, and a COLOR knob that recolors the whole plugin live without touching the sound.

Curve Control is the precise one. A dual-channel mix and mastering parametric EQ with six fully parametric bands per channel, Link/Dual/M-S modes, always-on harmonic saturation, and Delta monitoring so you hear exactly what the EQ is doing.

Alternate Timeline is the time machine. Six decades of mastering character in one processor - pick the era, set the blend, and the EQ curve, compression behavior, and harmonic profile all shift together.

Buy them separately and you're choosing one relationship with tone. Buy the collection and you have all three - creative, precise, and vintage - ready for whichever one the track actually needs.

The Entire Collection

Forty-Three Bands. Six Decades. Twenty-Nine Bucks.

You receive the complete versions of Third Rail, Curve Control, and Alternate Timeline. Every band, every mode, every era, every preset is included - nothing is trimmed down for the bundle.

One license key activates all three plugins. Each one includes three simultaneous activations, covering your studio machine, laptop, and backup rig.

Purchased separately, the three EQs total $97. During the introductory release, the complete collection is $29 - a real discount for owning the full range of what an EQ can actually be.

Third Rail

The Creative One.

A tube-driven stereo 31-band 1/3-octave graphic equalizer - real ISO center frequencies, one fader per band, ±24 dB of range. Push the INPUT knob hard and tube saturation kicks in on its own, the way it works on real hardware.

  • 31 real bands - full ISO 1/3-octave center frequencies, 20 Hz - 20 kHz.
  • Input-driven saturation - push INPUT hard for tube character, no separate drive knob.
  • COLOR knob - continuous hue, recolors faders and meters live, zero effect on the signal.

Curve Control mix and mastering EQ

Curve Control

The Precise One.

A dual-channel mix and mastering parametric EQ with six fully parametric bands per channel, three operating modes, always-on harmonic saturation, and oversampling up to 8x.

  • Link / Dual / M-S - ganged stereo, fully independent L/R, or Mid-Side processing.
  • Six parametric bands - high-pass, low shelf/bell, two mid bells, high shelf/bell, low-pass.
  • Delta monitoring - hear only what the EQ is adding or removing.

Alternate Timeline

The Time Machine.

Six decades of mastering character in a single processor. Pick the era, set the blend, and dial in the tone - each setting applies the EQ curve, compression behavior, and harmonic profile of that era's best rooms.

  • Six era presets - 1960s through Modern, each with matched EQ and compression character.
  • Bottom / Middle / Top - three-band tonal shaping layered on top of era processing.
  • Blend knob - full parallel processing chain, from a hint to full commitment.
